IMPROVEMENT IN CAR-BRAKES.

Specification forming part of Letters Patent No. l35,16l, dated January21, 1873.

To all whom it may concern:

Be it known that I, WM. H. M. SANGEE, of Bay Side, in the county ofKings, and State of New York, have invented an Improvement in Brakes forRailway Trains, of which the following is a specification:

This invention is made for stopping the train with rapidity, and givingto the engineer the control ofthe train, and at the same time relievingthe wheels from the wear and injury arising from the brake-blocksholding the wheels so firmly as to cause them to slip upon the track andwear tlat atplaces.

I make use ot a brake-bar at the front end of the engine beneath thecow-catcher or the frame, upon which brake-bar there are shoes to restupon the surfaces of the rails when the bar is pressed down by theaction ofthe lever to produce the friction required to stop the train.This bar is firmly supported from the cow-catcher or frame of thelocomotive-en gine, so as to withstand the greatstrain to which it issubjected; and the mechanism that acts upon the said lever is under thecontrol of the engineer, and by means thereof the train can be arrestedby him with great rapidity and without injury to the wheels.

In the drawing, Figure l is a side view representing the said inventionand part of the locomotive-frame; and Fig. 2 is a front elevation of thecow-catcher and brakes.

The engine is of any desired construction.

. I have shown theframe a, truck-wheels b, part of the boiler at c, andcow-catcher at d. The brake-barf is connected with the cow-catcher d, byhinges or joints. g is a lever, that has its fulcrum at t', and it isconnected at the upper end to the cross-lever k, and this has itsfulcrum at Ic', and is moved by a rope or chain,

Z, leading over the pulley m to the hand or brake-wheel o, so that theengineer can force the brake-bar down upon the tracks with great force,and the shoes r o', that are upon the under side ofthe bar f, serve toprotect the brakebar from wear, and also increase theadhesion to therails, so that the train can be stopped with rapidity. The brake-barf,and shoes with their actuating levers, are under control of theengineer, and are in position to aid in removing obstructions as well asoperating as a brake.

Steam power may be employed to actu-ate this brake 5 and when the shoesare Ilan ged they tend to keep the locomotive upon the track.

Springs may be employed to raise the brake bar from the track when notin use.

I do not claim a shoe pressed upon the track to act as a brake, as thishas been employed. Neither do I claim shoes applied to a locomotiveengine between the truck-wheels and drivers, as these have been made useof and actuatedby levers upon the engine, but they do not tend to removeobstructions; hence the truck-wheels or locomotive may be thrown fromthe track. In my improvement the brakeblocks and bar act astrack-elearers.

I claim as my invention- The brake-bar f hinged upon the cow-catch er,and provided with the shoes r r, in combination with the levers g and k,and rope or chain l, as and for the purposes set forth.

Signed by me this 7 th day of October, A. D. 1872.
